Does a chicken grow from the white or the yolk of an egg?
The germinal disc is located on the yolk, so that is where the initial cellular division takes place. But a chick can not develop with out both the yolk and the whites (albumen).

Yes, it definitely can be mistaken for a viable pregnancy. An ultrasound can usually help in determining whether it is a blighted ovum or a pregnancy.

Transabdominally, it is a blighted ovum if it measures >20mm without a visible yolk sac or >25mm without a visible embryo.
